1 Pressure & Flame Protection Tank Protection Valves

2 Tank Protection Valves Marvac manufacture an extensive range of products to protect low pressure storage tanks and vessels.these products help to prevent damage to the tank and also prevent the tanks contents from escaping, ensuring the safety of personnel and the surrounding environment. Marvac s team of engineers have unrivalled experience in dealing with tank storage applications, enabling them to assess each customers individual specifications to provide the optimum safety solution. Marvac products can operate within a range of -800 mbarg to 3.5 barg and -196 C to 250 C. However, Marvac s vast technical experience often allows these parameters to be extended on consultation with the factory. Pressure/Vacuum Relief Valves - A range of pressure only, vacuum only and combined pressure and vacuum relief valves to alleviate the problems caused by the thermal effects and the filling and emptying of storage tanks and vessels. Combination Flame Arresters/Relief Valves - A comprehensive range of Flame Arresters is available to work in combination with the MARVAC Pressure/Vacuum Relief Valves. Pilot Operated Relief Valves - To provide accurate pressure relief when operating near to the design pressure of the tank and also to overcome the problems of backpressure generated at the discharge of the valve due to pipework, scrubbers etc. Tank Blanketing Valves - Dedicated to provide inert or rich blanketing of storage tanks to reduce harmful fugitive emissions and reduce the evaporation of product. Emergency Vent Manway and Gauge Hatch - To provide over pressure protection in the event of the tank being subjected to fire exposure and to provide access to the vessel from the top for internal inspection. Gauge hatches to provide for product level measurement and sampling.

3 Testing and Development The high levels of quality achieved by Marvac are testament to their policy of rigorous testing and continual product development. Marvac possess an in-house calibrated test facility, enabling extensive testing and development of their products. Marvac products are designed using 3D solid modelling techniques, finite element stress analysis and computational fluid dynamics to enhance and accelerate the development process. Materials Marvac products are available in a wide range of standard materials including stainless steel, carbon steel, aluminium and cast iron. Special alloys can also be incorporated e.g. Hastelloy, Monel and Duplex. For corrosive applications where stainless steel is not suitable products can be manufactured in a range of plastics such as polypropylene, PVDF and Halar. Accessories A wide range of accessories are available, designed to suit systems requirements.the range includes pressure gauges, flow plugs, integral pressure sensing and steam jacketing. Proximity switches for remote indication of valve operation. Applications Storage Tank Applications Sewage Plants Waste Water Treatment Breweries/Distilleries Pharmaceutical Chemical Shipping Petroleum Powder Silos
